World's largest Hawaiian shirt, according to the Guinness Book of World Records. It hangs in the window of the Gaslamp's Hilo Hattie store at 301 Fifth Avenue. Tailors at Hilo Hattie, one of Hawaii's biggest fashion retailers, made the shirt for its Kamehameha Day parade float in 1986. It measures 14 feet around the chest, 5 feet around the neck, and needed 26 yards of fabric.
